What would raise the skill-ceiling/floor?
There is a general consensus, though vaguely-defined, that among other changes most killers should be brought into line with the more-favoured ones. Disregarding some of the equivocations given(that 'not all killers are meant to be good' as stated on a livestream), there needs to be some idea of how this should happen.
I will leave aside related-topics such as possible future Nurse changes; there is going to be much more debate on this as we get closer to the unknown date when that will actually happen. One thing to touch on though is that the Nurse establishes something which the strongest killers all share: they are the most unique and all have a higher skill-ceiling and/or floor. They require more effort and practice, but proportionately give more for the return-on-investment than other killers do. For clarity, these killers are; Nurse, Hag, Spirit, Billy and Huntress.
The devs have a tendency to 'solve' problems by introducing or changing perks, or new characters rather than impementing solutions as core game features. Whilst there might be a strong taste for skill-based perks and some disdain for perks that are 'free-benefits', that should be held as a separate discussion.
We don't just simply need future killers to require more skill in return for more power, some existing ones need bringing up to date along those lines. This is in conjunction with some of them having QoL issues that need addressing, either separately or as part of any future 'up-skilling' revamp. Like the existing high-skill killers, they also need their skill-requirements to be expressed in a unique way. Aiming a blink is not the same as aiming a hatchet or a chainsaw-sprint or a phasing-ambush.
So, do you have a specific character you enjoy but just wish they had a bit more 'oomphf' at the cost of requiring more effort from you? How would you make it work?
